Abstract
In this paper, the digital speckle correlation method (DSCM) is selected as the experimental means to calculate the J integral of foil material. The deformation fields in the crack tip region are measured and their contour maps are shown. The formula using deformed field to calculate J integral is derived. Through calculating J integral of foil material by the DSCM, it is shown that this experimental method is a useful test technique in studying the mechanical behavior of film or foil materials.
